1). Qhov mob thiab qhov kub thiab txias cov receptors nyob rau hauv daim tawv nqaij ntawm daim tawv nqaij yog piv txwv ntawm cov neurons uas muaj dawb cov hlab ntsha kawg . Kuj tseem nyob hauv lub dermis ntawm daim tawv nqaij yog lamellated thiab tactile corpuscles, neurons nrog encapsulated hlab ntsha kawg uas teb rau siab thiab kov.
Ib yam nkaus, tib neeg nug, uas yog piv txwv ntawm cov neeg txais khoom kaw?
Piv txwv yog mob cov receptors , kub cov receptors , Merkel disks (kov), plaub hau hauv paus plexus. Encapsulated receptors muaj lub tsiav tshuaj tshwj xeeb uas ua rau cov hlab ntsha xaus. Golgi cov leeg hauv nruab nrog cev - nthuav tawm cov leeg, sib zog ntawm cov leeg.
dab tsi yog encapsulated hlab ntsha kawg? Mechanoreceptors hauv daim tawv nqaij tau piav raws li encapsulated los yog tsis muaj kev txwv. Ib qho dawb paj xaus yog unencapsulated dendrite ntawm lub paj hlwb; lawv yog cov feem ntau cov hlab ntsha kawg hauv daim tawv nqaij. Pub dawb cov hlab ntsha kawg yog rhiab rau qhov kev mob siab rau, kub thiab txias, thiab ua kom pom kev.
Kuj lo lus nug yog, 5 hom kev hnov qab neeg hnov dab tsi?
Tsib qhov yooj yim hnov qab tus neeg txais qhov kawg muaj nyob hauv tib neeg lub cev: cov thermoreceptors kuaj pom qhov hloov pauv ntawm qhov kub thiab txias; cov kws kho tsheb teb rau lub cev deformation; nociceptors teb rau qhov mob, photoreceptors /electromagnetic receptors yog qhov pom tau ntawm cov retina; chemoreceptors ntes hnov tsw, saj, sab hauv
Dab tsi yog peb hom kev hnov qab cov neeg txais?
Sensors receptors feem ntau yog cais ua chemoreceptors, thermoreceptors, mechanoreceptors, lossis photoreceptors.
Pom zoo:
Dab tsi tsuas yog lim los ntawm cov hlab ntshav los ntawm glomerulus thiab tsis rov qab nqus mus rau hauv cov hlab ntshav tab sis tawm los ntawm cov zis?
Creatinine yog cov khoom pov tseg los ntawm cov leeg tawg thiab raug tshem tawm los ntawm cov ntshav los ntawm glomerulus ntawm nephron. Nws tsuas yog cov khoom uas tsuas yog lim tawm ntawm cov ntshav tab sis TSIS tau rov ua dua rau hauv lub cev. Nws raug tso tawm los ntawm cov zis
Hom hlab ntshav twg txuas cov hlab ntsha thiab cov hlab ntshav?
Hom hlab ntsha Capillaries yog feeb nyias-walled hlab ntsha uas txuas cov hlab ntsha thiab venules; Nws yog los ntawm cov capillaries uas cov as-ham thiab cov pov tseg tau pauv ntawm cov ntshav thiab cov ntaub so ntswg ntawm lub cev
Yam kev hnov lus tsis zoo dab tsi hauv kev hais lus hauv kev hnov lub suab hnov suab ntsuas?
Kev hais lus audiometry yog ib qho cuab yeej tseem ceeb hauv kev ntsuas kev hnov lus. Ua ke nrog lub suab ntshiab suab, nws tuaj yeem pab txiav txim siab qib thiab hom kev hnov lus tsis hnov lus. Speech audiometry muab cov ntaub ntawv ntawm kev lees paub lo lus thiab hais txog kev tsis xis nyob lossis ua siab ntev rau kev hais lus
Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
